Product Description

Products Description

WB1-125R dedicated circuit breaker for photovoltaic grid-connection (hereinafter referred to as dedicated circuit breaker for photovoltaic grid-connection) is suitable for distributedl photovoltaic grid-connection power consumption, which can detect and judge the voltage onl photovoltaic distribution lines, automatically delay opening when overvoltage, undervoltage orl voltage loss occurs on photovoltaic distribution lines, and automatically close when the voltage returns to normal.
       WB1-125R self-recovering overvoltage and undervoltage protector (hereinafter referred to asl special circuit breaker for buildings) is suitable for low-voltage distribution systems for household land similar purposes. It can automatically turn off when the line fault causes overvoltage or undervoltage, automatically detect the line voltage and automatically close when the line voltage returns to normal.
      
       Photovoltaic circuit breaker/building circuit breaker is suitable for rated isolation voltage of 500V, AC 50Hz or 60Hz, rated working voltage of 230 V/400 V, rated current of 125A and power distribution lines.
      
       The special photovoltaic circuit breaker meets IEC60898-1, GB/T 10963.1 and Q/GDW 19722013 standards;
      
       The special circuit breaker for buildings meets IEC60898-1, GB/T10963.1 and JB/T127622015 standards.

Dimension

The circuit breaker should be installed vertically. When the handle is in "O/OFF". the contact is in the off state. When the
handle moves upward, the contact moves in the closing direction. 
       See Table 3 for the nominal cross-sectional area of copper wire
for connection matching the rated current of circuit breaker.
      
       To install WB1-125R, please tighten the copper conductor with a torque of 3.0Nm. At the same time, after the installation is completed, check whether the copper conductor is fastened by shaking the conductor. If it is not fastened, please tighten the copper conductor again with the torque required above.
